' 4 Claims. (01. 6818) I 1 This invention relates to' improvements inclotheswashing machines and'pertains particularly to a machineof'the.type wherein clothes are encased inamovingre'ceptacle, r v

The primaryobject ofthe present inventio is toprovideIa novel andeflicienttype of clothes washer which will wash through thereciprocation of the clothes through the water but will effectivelyprotect the "clothes against pounding or other action which might tendto injure-the fabric. a 1

Another object' of the invention is to provide in a washing machine'having a reciprocating clothes receptaclea novel means for impartingrotary motion to the receptacle in addition to its reciprocatory motion.

The invention will be best understood from a consideration ofthefollowing detailed description taken in connection with theaccompanying drawing forming part of this specification, with theunderstanding, however, that the invention is not confined to any strictconformity with the showing of the drawing but may be changed ormodified so long as such changes or modifications mark no materialdeparture from the salient features of the invention as expressed in theapp nded claims.

In the drawing:

Figure 1 is a view partly in elevation and partly in vertical section ofthe machine embodying the present invention;

Figure 2 is a sectional view taken substantially upon the line 2-2 ofFigure 1;

Figure 3 is a sectional view taken on the line 3--3 of Figure 1;

Figure 4 is a view in elevation of a fly wheel of the structure. 7

Referring now more particularly to the drawing wherein like numerals ofreference indicate corresponding parts throughout the several views, thenumeral 1 designates a receptacle for the clothes washing solution, thebottomof which is preferably semicylindrical as indicated at 2 in Figure2. The top of the receptacle is closed by the cover 3 and access may behad to the interior for inserting and removing clothes, through I a doorstructure, such as is indicated by the nut meral 4, which is disposedabove the water line of thereceptacle.

Within the receptacle the opposite end walls are provided with thespaced parallel guides 5 which form opposing channels 6.

Extending across the receptacle from one end downwardly extending endarms 8, which slidably position in the'chann'els 6.

Disposedben'eath the beam 7 and between the free endsof'the arms'8 isaperforatedreceptacle 9 which is lpr'eferably cylindrical in. formandwhich carries. trunnions '10. at its ends whichare pivotallyconnectedawith :the arms8. This re.-

ceptacle is provided withxa door '11- which. closes an opening inthe-wall thereof through which clothes are put in and removed:

The central .part of the-cover 4 is provided with an openingl12through'which there. extends upwardly the vertically reciprocablezrod 13which 7 at. its lower end is securely; connected with the bar 7 and atitsupper end passes through an aperture 14 formedtin' a guiding crosshead 15. Q 1

This-head 15'is supported above-the top of the receptacle by thestandards :16 which are mounted on the receptacle top in the mannerillustrated and which are provided with shaft bearing openings 17 forthe purpose about to be described.

Mounted upon the cover 3 is'a pair of bearings each of which isindicated by the numeral 18, which are in alinement one with the otherand I with the bearingapertures 17 in the standards 16. Each of thesebearings 18 'coact with a bearing aperture 17 for the support of a shaft19'which at its outer end carries a fly wheel 20. At the inner end ofeach shaft 19 there is mounted a gear 21 and these gears are connectedby a wristpin 22 which is eccentrically disposed with respect thereto asshown in Figure 3.

Connected with the wrist-pin 22 is one end of a connecting rod 23 whichhas its other end pivotally connected with the rod 13, at the point 24.Mounted at opposite sides of the receptacle 1 and to one side of thestandards 16, are the bearing units 25 between which is rotatablysupported a drive shaft 26. This shaft carries two pinion gears 27 andupon one end has mounted the pulley wheel 28 by means of whicha drivingbelt or other power transmitting means may be connect- 7 ed with theshaft. The pinions 27 are in mesh with the gears 21 and it will thus beseen that when they are driven or rotated power will be transmitted tothe gears 21 and thus cause reciprocation through the wrist-pin 22 andconnecting rod 23, to the drum carrying shaft 13. The drum will thus beraised and lowered in the receptacle and the cleaning fluid therein willbe caused to pass forcibly through the apertures of the drum. t

In order that the drum may be rotated at the same time that it isreciprocated, there are secured to one side wall of thereceptacle 1 uponsame passes the finger.

the inner side, a pair of spring arm-s, each of which is indicated bythe numeral 29. These arms are connected at one end and have their otheror lower ends curving inwardly away from the wall so as to frictionallyengage the wall of the drum as the latter is forced down past them.

It will thus be seen, upon reference to Figure 2, that when the drum isall the way down and then is moved upwardly the free ends of thesespring fingers will cause slight rotation of the drum through theirfrictional contact with the wall of the same. a

It will thus be seen from the foregoing that a novel and eflicientmachine is provided in which the most delicate material may be washedwithout damage as the only strain placed upon it is created by the waterflowing through the apertures of the drum.

Having thus described the invention, what is claimed is:-

1. A washing machine comprising a receptacle,- a pair of guides upon theinner surfaces of opposite walls of the receptacle, a frame structurehaving a pair of vertical members each slidably engaging a guide, anapertured'drum rotatably mounted between the vertical members of theframe, a rod connected with the :frame and extending vertically'throughthe top of the receptacle, power means upon the top of the receptacleconnected with said rod for reciprocating the latter, and a resilientfinger mounted within the receptacle upon a wall of 'thesame and havingafree end arranged to 'f rictionally engage the drum and impart rotarymotion thereto as the 2. A washing machine comprising a receptaclehaving a top, a pair of guides within the receptacle and upon oppositewalls thereof, a substantially U-shaped inverted frame within thereceptacle having the side portions thereof slidably engaging saidguides, a rod connected with said frame and passing upwardly through thetop of said receptacle, an apertured drum rotatably mounted between thesides of said frame, a pair of shafts mounted in alinement upon the topof the receptacle, a gear mounted upon each of said shafts, said gearsbeing in spaced relation and the 'ends of said shafts spaced apart, awrist-pin eccentrically connecthig said gears, a connecting rod couplingsaid wrist-pin with said .lflI'St rod, balance wheels mounted upon saidshafts, and means for driving said ears.

3. In a-Washing machine, a receptacle, a cylinder within the receptaclehaving a foraminous wall, a vertically movable frame in the receptacle,means supporting the cylinder at its ends in horizontal position in theframe for rotation, means for vertically reciprocating said frame andthe cylinder therein, and means engaging the cylinder intermittentlyduring its vertical movement in one directiononly for causing the sameto rotate always in the same direction.

4., Ina washing machine, a receptacle, a structure movable vertically inthe receptacle, a horizontally disposed cylinder having a foraminouswall and mounted for rotation in a horizontal plane on thestructurdxmeans for effecting the vertical movement of the structure andthe cylinder, and a resilient finger fixed within the receptacle anddisposed to be passed by the cylinder when the latter is moving in onedirection and engage. the cylinder when itv is moving in the oppositedirection-to impartan intermittent rotary movement to the cylinder.
